# Backstory:
#
# I wrote this script because one [1] of my videos got some hits with
# irrelevant keywords. I understand that would be frustrating when the searcher
# wants to find a progress bar in Tk, but gets a video hit about progress bar
# in terminal. So I did some reading and coding to produce this code.
